AUTOMOBILE-JACK.

Specification of Letters Patent.

Patented Oct. 6, 1914.

Application filed July 15, 1912. Serial No: 709,833.

To all whom it may concern Be it` known that l, FRANKLIN A. Semi can. acitizen of the United States, residing at Des Moines, in the county ofPolk and State of Iowa, have invented a certain new and usefulAutomobile-JackI. of which the following is a specification.

The object of my invention is to provide an automobile jack of simple,durable and inexpensive construction, .which is designed to be mountedand carried on the axle of an automobile, upon which the vehicle may bereadily moved about.

A further object is to provide such a jacl'r,

which may be swung .to position where`1t will be out of the way when. 1t1s not 1n use and easily and readily secured in such posi"- tion.

A further object is to provide an automobile' jack of the kindmentioned, provided with a hinged lever handle which may be folded overagainst the jack proper in such i position that it cannot swingdownwardly or be in the way when the jack is ih its raised position.

A further object which may be readily and easily released from itsraised position and dropped to position for raising the car thereon, and

provided with a hinged handle which will stand in proper position foruse when the jack is lowered, and with means for securing said handleagainst movement whenthe jack is in its raised position.

My invention consists in certain details, in the construction, nation ofthe various parts of my device, whereby the objects contemplated areattained, as hereinafter more fully. set forth,`

pointed out in my claim, and illustrated 'in the accompanying drawings,in which- Figure 1 shows a front elevation of an automobile 4showing twoof my jacks installed on the axle, one of them being in its raisedposition and the other being in its lowered position and ready for use.Fig. 2 shows a detail, sectional, view of the said axle with my devicethereon, taken from the side of the automobile. Fig. 3 shows a central,vertical section through my improved automobile ]'ack. Fig. 4 shows adetail, sectional view of the ratchet. Fig. 5 shows a central,transverse7 vertical, sectional view through the plate which is designedto be secured to the axle and the plate on which the jack proper ismounted.

is to provide such a jack' arrangement and combi- `.I une 6, 1912. Anarm 21a Fig. 6 shows a detail view of the face of the plate which issecured to the axle.

In the-accompanying drawing I have used the reference vnumeral 10toindicate generally the body of an automobile. 'I have shown a :frontaxle 11 and front wheels 12 mounted thereon.

My improved automobile jack is designed to be mounted'on the laxle andto be carried there although it 'may be readily detached when desired.On one side of theaxle I provide a plate 13 extending above and belowYthe axle. On the opposite side I provide a similar plate 14. Above andbelow the axle are a number of bolts 15, whereby the plates 14 and 1?are secured together, and mounted on the axle. It willbe understood thatthe adjacent surfaces of the plates'13 and 14'may be of any suitableshape to fit the axle and that the outer surface of the plate 14 issmooth and fiat. A similar plate 16 is rotatably mounted adjacent to theforward face of the plate 14 by means of a bolt 17 which extends throughthe plates 14 and 16. The bolt 17 `is preferably provided with a, headand a nut which are countersunk respectively in the inner surface of theplate 14 and the outer surface 'of the plate 16. The plate 16 isdesigned to rotate freely on the bolt 17. Formed on the outer surface ofthe plate 16 is a lug 18. Extending through the lug 1S and throlgh theplate 16 is an opening in which is mounted a screw 19 on which is a head20. The use of the screw 19 will be hereinafter more fully described.Formed on the outer surface of the plate 16 and preferably extendingacross the center thereof, is an elongated lug or bearing 21 which isinternally screwthreaded.

Extended through the internally screwthreaded bearing 21 is ascrewthreaded rod 22. On the lower end of the rod 22 is fixed a ratchetwheel 24 havinga downwardly extending portion 35. Below the ratchet 24is a cylinder 101 in the upper end of which is formed a socket toreceive the lower portion of the extension 35 and the lowerend of the-rod 2.2.l For operating the ratchet 24 and thereby rotating the rod 22,I have provided a pawl and lever similar in construction to the ratchetand pawl described in my application for patent, Serial No. 702,106,filed is providedwith an opening 40 which turns freely on the rod 22 andis mounted thereon just above the and through the i ed between the arms23a the ratchet 24 and the the plate 16 is a spring 60 for holding' thelto receive the screw 19.

Y opening 10".

ratchet 24. An arm 23a is rotatably mounted on the downward extension-35-between cylinder 10a. The ratchet 24- and the rod 22 are securedtogether and are rotatably mounted in the upper end of the c linder 10aby means of a' pin 37 whichv ext nds through the rod 22 'xtension 35 oneach side of the rod 22. Each end of the pin 37 is received in aninternal annular groove 36 in the socket in the u per end of thecylinder 10a, being original y inserted through the tending through oneside of the cylinder. 10 into" the groove 49, is a removable pin 54 bywhich the cylinder 46 is held in the opening 49. lhe lower end of thecylinder 10 is externally screwthreaded and mounted on said ,lower endis a nut 55. By screwing the nut 55 downwardly against the bracket 50,said bracket may be locked against rotation. It will be noted that thebracket 50 is so 'constructed that the wheel 51 is mounted od' centerwith relation to the cylinder 461 lt will therefore appear that when thejack is in its raised position, as shown in Fig. 1, the wheel 51 may beturned downwardly and the lever handle 42 moved to position above thebody of the jack and fastened beneath the spring and the pawl 25 locked.The caster wheel may be locked .against swivel movement by the nut 55.The lever arm will then be held in position and cannot rotate on accountof the fact that 51 will engage the axle and resist any tendency of thelever arm to swing downwardly and forwardly.

My improved jack has the advantage of being permanentlyi and yetdetachably secured to the axle so that it is always installed inpositionfor use. When not in use, it may be moved to its raisedposition, and be entirely out of the way. 1t may be quickly and easilydropped to its position for use and locked therein. 'llhe lever arm ymaybe removed from the engagement with the spring' 60 and moved to positionfor use. lf my jacks are installed on both front and rear axle, thevehicle may be freely moved on them. rlhe caster wheel 51 may bepermitted a free swivel movement or may be locked against such movement.

A claim as my invention:

1n a device ofthe classdescribed, the combination of a vehicle axle, afplate provided with a pivot and a number o openings concentric withsaid pivot, means for securing said plate to said axle, a second platemounted upon the pivot of the first mentioned plate, means foradjustably securing a jack to said second plate, and a screw threadedpin in said second plate to coact with the openings in the rst plate tolock a jack in anyone of a number of positions relative to the axle.

At their outer ends, the arms 23a and the arm 21a are held spaced apartby a block 40. A bolt 41 secures the arms 23El and 21a and the block 40together. Pivotally mountand 21a and adjacent to the ratchet 24 is apawl 25, constructe similar to the pawl in my former applicationhereinbefore identified. Pivoted to the outer end of the arm 21a toswing in a vertical plane when my jack is in its lowered position, is alever arm 42. lThe downward movement of the lever larm 42 is limited bythe outer end of the block 40, as clearly shown in Fig. 3. 0n theoutersurface of lever arm in its folded position as hereinafter morefully described.

For securing the jack in its lowered. or in its raised position, Ishaveprovided the following means: Mounted in the plate 16 is a thumb .screw19 hereinbefore described. In the plate 14 l have provided ascrewthreaded opening 44 designed to receive the screw 19 when the jackis in its lowered position. When the screw 19 is not received intheopening 20, the jack may be swung to position parallel with the axle, asshown at th'e right hand side of Fig. .1. I ave provided in the plate 14a screwthreaded opening 45 By screwing the screw 19 into the opening 45when the jack is in its raised position, the jack may be secured in saidposition.

ln thelower end of the cylinder 10EL is an upwardly extendingcylindrical opening 45. Mounted-in the opening 45 is a cylinder 46 ont-he upper end of which is a head 47 and just below the head 47 andslightly spaced apart therefrom is a shoulder 48. It will be seen thatbetween lthe shoulder 48 and the head 47 is formedl a groove 49. Fixedon the cylinder 46, below the cylinder 10a isa bracket I50 in which ismounted a caster Witnesses: wheel 51, Surrounding the cylinder 46 inBEssm E. DEAL, the opening 45. are A. G. Hamm.
